Manchester United manager Louis van Gaal is to face questions over his transfer policy on 10 July as he holds his first press conference since the end of last season.

Memphis Depay will be officially unveiled during the press conference, but attention will quickly turn the lack of signings made by United this summer, which has seen the side restricted to just one addition.

Italian full-back Matteo Darmian is on the verge of moving to Old Trafford according to Torino, while AS is reporting that Valencia defender Nicolas Otamendi will move to Old Trafford.

Van Gaal is likely to be probed over the progress of these deals and whether the club will look to replace any of the host of players who have departed this summer.

David de Gea continues to be linked with a move to Real Madrid, with Iker Casillas set to join FC Porto, but the La Liga giants are in no rush to end the saga reports The Mirror.

Tom Cleverley and Nani have left the club for Everton and Fenerbahce respectively, while Sky Sports understands that Robin van Persie is on the verge of following the Portuguese winger to the Super Lig at Galatasaray.

Van Persie's departure would represent the second big-name striker to leave the club in the off season, after United decided against making Radamel Falcao's loan deal a permanent one.

Javier Hernandez has broken his collarbone, and remains linked with a move to Sevilla where he would replace Carlos Bacca.

Van Gaal therefore faces going into pre-season with just one recognised senior striker – captain Wayne Rooney. How the Dutch coach will beef up United's attacking options will likely be among the questions to come.

The press conference is also the final briefing Van Gaal will make before the club embark on their pre-season tour of the US.
